The developer has shared a brief tutorial that would allow the interested hackers to run Windows RT 8.1 on Lumia shipped with Windows Phone 8.1 operating system. We are not responsible for any damage that may occur while flashing the unsupported operating system.

If you would like to keep your Windows Phone alive by not necessarily using the typical ways of running hacked apps, you might want to install Windows RT. Windows RT 8.1 was originally created for PCs or Tablets, as a result the experience of hacked Windows RT 8.1 on Lumia Windows Phone won’t work as expected.

The operating system appears to be running fine, though it lacks support for audio and cellular connectivity, WiFi, full desktop and Start screen works smooth. “You need to be familiar with ACPI(reading table sources), UEFI, Windows Phone partition, Windows deployment stages, Windows Driver Development, Windows Kernel Debugging and patient,” he said.

“For people asking cellular: No. Windows and Windows Phone shares a different RIL stack (even in post-OneCore era), unless you develop a set of tools that deal with AT commands, you will not get cellular connectivity on Windows RT on Lumias,” he added.
